ERJ3EKF3301V是松下(PANASONIC)推出的精密级厚膜贴片电阻,专为小型化、高可靠性电子设备设计,具备稳定阻值特性与宽温适应性,适用于工业控制、消费电子等多领域场景。
该电阻属于松下ERJ系列精密厚膜贴片电阻,核心定位为中高精密、小型化、工业级适配的基础电子元件:
标称阻值为3.3kΩ(型号代码“3301”对应:330×10¹Ω),精度±1%——即在常规工作条件下,阻值偏差控制在±33Ω以内,可满足传感器信号校准、电源电压反馈等对精度要求较高的场景。
温度系数为**±100ppm/℃**,即温度每变化1℃,阻值变化±0.01%。在工作温度范围(-55℃~+155℃)内,最大阻值变化约±2.1%(155℃与-55℃温差210℃,210×100ppm=0.021),稳定性符合工业级设备的宽温要求。
覆盖**-55℃~+155℃**,适配寒冷地区户外设备、汽车发动机舱周边、工业炉附近等极端温度场景,避免低温下阻值漂移、高温下性能衰减。
根据松下ERJ系列型号命名规则,“ERJ3E”前缀对应0603封装(英制:0.06×0.03英寸;公制:1.6×0.8mm),该封装具备以下特点:
松下厚膜电阻采用成熟工艺与严格质量控制,具备以下可靠性优势:
ERJ3EKF3301V以紧凑封装、稳定阻值、宽温适应性为核心优势,成为小型化、高可靠性电子设备的理想基础元件,覆盖工业、消费、汽车等多领域应用,符合松下对精密电子元件的品质要求。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.
The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
